This update is all about making the Gemini Command Line Interface (CLI)—a tool that lets developers interact with Gemini directly by typing commands into their computer's terminal—more secure, reliable, and organized. It introduces new testing tools, plugs a security loophole, and fixes several bugs that could cause the program to freeze or get stuck.
What's new
- New Evaluation Tools: Added a new command (
eval:inventory) and a "static analyzer." These tools help developers scan, track, and organize their "evals" (tests used to measure how well the AI is performing) and export the results in JSON, a standard, easy-to-read data format. - Air-Gapped Cloud Support: The CLI now supports secure "air-gapped" environments. "Air-gapped" means a computer network is completely isolated from the public internet for maximum security, which is common for sensitive government or corporate work.
Improvements
- Consistent Tool Outputs: Standardized how different tools format and display their results, making the text on your screen much cleaner and easier to read.
- Cleaner Settings: Automatically moved the
coreToolsconfiguration setting to a new, more organized home undertools.core.
Fixes
- No More Quota Hangs: If you run out of API quota (your limit for sending requests to Gemini), the CLI will now stop immediately and tell you, instead of getting stuck in an endless loop trying to reconnect.
- Security Patch for Skill Installs: Fixed a "path traversal" vulnerability. This is a security bug where a malicious file could trick the CLI into accessing or changing private files on your computer during a skill installation.
- Tmux Background Fix: Fixed a bug where using
tmux(a popular tool that lets you split your terminal into multiple windows) would trick the CLI into thinking it was running in the background when it wasn't. - Text Formatting Fix: Fixed an issue where multi-line text containing quotation marks would break when processed by the command line.
- Scheduler Freeze: Fixed a "starvation" bug where the internal task scheduler would get overwhelmed and freeze up.
